Book Description
As rising levels of mercury in the environment pose an increasing threat of toxicity to humans and wildlife, several laws already call for industries to reduce mercury emissions at the source. Ecosystem Responses to Mercury Contamination: Indicators of Change outlines the infrastructure and methods needed to measure, monitor, and regulate the conce

Book Description
Report on how mercury (Hg) was examined in top-predator fish, bed sediment, and water from streams that spanned regional and national gradients of Hg source strength and other factors thought to influence methylmercury bioaccum. Sampled settings include stream basins that were agr¿l, urbanized, undeveloped, and mined. Predator fish were targeted for collection, and composited samples of fish were analyzed for total Hg (THg), as most of the Hg found in fish tissue is MeHg. Samples of bed sediment and stream water were analyzed for THg, MeHg, and characteristics thought to affect Hg methylation, such as loss-on-ignition and acid-volatile sulfide in bed sediment, and pH, dissolved organic carbon, and dissolved sulfate in water.

Book Description
Understanding Environmental Pollution systematically introduces pollution issues to students and others with little scientific background. The first edition received excellent reviews, and the new edition has been completely refined and updated. The book moves from the definition of pollution and how pollutants behave, to air and water pollution basics, pollution and global change, solid waste, and pollution in the home. It also discusses persistent and bioaccumulative chemicals, and pesticides, and it places greater stress on global pollutants. The relationship between energy generation and use, and pollution is stressed, as well as the importance of going beyond pollution control, to pollution prevention. Impacts on human and environmental health are emphasized throughout. Students are often invited to come to their own conclusions after having been presented with a variety of opinions. This textbook provides the basic concepts of pollution, toxicology and risk assessment for non-science majors as well as environmental science students.

Book Description
One of California's most remarkable wetlands, Suisun Marsh is the largest tidal marsh on the West Coast and a major feature of the San Francisco Estuary. This productive and unique habitat supports endemic species, is a nursery for native fishes, and is a vital link for migratory waterfowl. The 6,000-year-old marsh has been affected by human activity, and humans will continue to have significant impacts on the marsh as the sea level rises and cultural values shift in the century ahead. This study includes in-depth information about the ecological and human history of Suisun Marsh, its abiotic and biotic characteristics, agents of ecological change, and alternative futures facing this ecosystem.
